It is so nice to see this list come to life again. I just wanted to point out that the inbound drop rate was merely .03% in the first email.
Elsewhere we keep hearing of 1-2% drop rates being common, and I just aint seeing it in any of the larger scale data I have been getting from the libreqos deployment. Maybe that´s how fifos collapse in slow start a lot more than we have ever observed. Maybe it is retransmits going wild at 250ms worth of buffering. scale=10 10688/29185742 .0003662062 I still have to sit back and admire you all for this magnificent achievement of cake. I am not really the gloating sort, but seeing juniper go up for sale to hpe today, at a firesale price, is oddly satisfying. https://blog.cerowrt.org/post/juniper/ On Tue, Jan 9, 2024 at 10:40 AM Nils Andreas Svee via Cake <cake@lists.bufferbloat.net> wrote: > > You’re unlikely to do any real harm though, but the warning is there cause > you can potentially soft brick your router using it.
